I can only talk about the T7 RRD. I have tried 9, 12 and 15. I get rid of the 12 because there where a lot of overlap between those kites wind ranges.

Type 7 15 using a Type wave 2 bar:

-low end: same as with the free style bar, 11 knots aprox.

-hi end: never get to that limit, when more than 18 I take the 9, but over 25+ knots for sure... when you extend your arms the kite lose almost all the power.

-bar press: Very, very low... if you use the freestyle bar is very low as well but it get a little harder when you approach the hi end.

-stability: very good

-turning: the fastest turning kite I have ever tried in each size. Though the Type wave is as fast as the type 7 if not faster.

-construction: Excellent, the main pro is the segmented LE. Those little segments make a hard, stable, and very rounded leading edge. And every little piece of the canopy could be easily repaired with little cost.

Now, this is not the perfect kite for everyone, I have to add what is the main flaw of this kite: It jumps a lot, but it has poor hang time. It doesnÃ‚Â´t glide like other hi aspect kites out there. But anyway it is not intended for flying and old school tricks but for wakestyle and power moves.

Personal opinion, the F-one tribal is the nuts, better than the North Vegas in every respect. waiting to try it out as http://www.allgoodfun.com have demo tribals in stock.
more depower, very fast in the air, big jumps everything about a C kite and a Bow kite in one.

Tried the 9mtr, 11mtr and 13mtr, they whole range seem to be just nothing short of awesome !!, as you say depower, lifeline are more than i expected, think i may have a whole quiver of Tribals - just got to decide on the colours.
